Description

Optical screen key disinfection device

The invention relates to a disinfection device, in particular to a disinfection device for optical screen keys.

Contact infection is one of the ways of spreading infectious diseases. In order to avoid contact infection, people need to wash their hands after touching public objects, such as handrails, elevator buttons, and public touch screens (such as ATMs, tour guides, etc.). Virus. In areas where hand washing is not convenient, alcohol, dry hand sanitizer or disinfectant that can kill viruses or make viruses inactive will be used to disinfect hands. For public use, such as handrails, elevator buttons, and public touch screens, they are regularly disinfected by wiping with diluted bleach.

However, the method of regularly wiping with diluted bleach water for disinfection is quite labor-intensive, and thus the cost is high. Moreover, the disinfection method of manual wiping is prone to omissions, and it is difficult to ensure the sanitation and safety of the environment. In addition, in practice, it is impossible to disinfect items such as elevator buttons and public touch screens after each use. Therefore, people who pay attention to health and safety often use keys, pens and other items to press when using elevator buttons, public touch screens and other items, resulting in a rapid loss of life.

On the other hand, wiping with diluted bleach will corrode the elevator buttons and public touch screens, resulting in rapid oxidation and damage, and when the diluted bleach is too much, it may also cause damage to the elevator buttons and public touch screens due to infiltration. The electronic parts of the screen are damaged due to moisture.

The main purpose of the present invention is to disclose an optical screen button disinfection device, which can automatically disinfect and avoid the risk of contact infection.

The two ends of the transparent film are respectively wound and fixed on the two film rotating shafts, the transparent film goes around the plurality of rolling shafts and respectively surrounds the two disinfection elements, and the transparent film covers the two through the engagement of the plurality of rolling shafts input interface. The two rotating shafts driving element can respectively drive the two film rotating shafts to rotate, so that the transparent film covering the input interface can move to the disinfection range.

Accordingly, the present invention allows the transparent film to cover the input interface, so the user can operate the input interface through the transparent film without directly touching the input interface. And after the user finishes operating the input interface, the transparent film covering the input interface can drive the two film rotating shafts to rotate through the two rotating shaft driving elements, and drive the transparent film to move to the disinfection range, so as to pass the The second sterilizing element is sterilized, so it can be ensured that the transparent film touched by different users has been sterilized, so as to avoid the risk of contact infection.
